To all whom may concern:

Be it known thatl, Fniiivs 0. 301mm, a citizen of the United States, re t Seattle, in the county of King and .f lvashington, have invented a new an u eful Improvement in donating Tools, of wh ch the following is a specification.

The object of my invention is the provision of. a tool especially adapted for use in brick masonry wherein it desired to make grooved joints in the mortar between bricks as laid, either to give the work a more pleasing appearance, or for the reception of mortar used in a joining finish.

To this end, I provide a tool made ofa single strip of sheet metal so cut and bent as to embody a bricklayers implement, light in weight and handy to use; one that will cut away the soft rough mortar between laid bricks and make a suitable, evenly gauged recess therein for the purposes mentioned. The tool is simple in construction, effective in operation, and can be produced at a lower cost, so far as known to me, than any other device in its class.

In the accompanying drawings Figure 1 is a view, in perspective,'showing the tool in operative position, and in connection with bricks and mortar joints.

Fig. 2 is a front view of the device complete.

Fig. 3 is a side view of the tool, including brickwork and a mortar joint, illustrating the operation of the device in cutting and gauging a groove.

Referring more particularly to the drawings, A designates the tool complete, formed from one piece of metal, and made preferably of sheet steel. B denotes its flat body portion, and C a tongue out out of the body and ofiset, as better shown in Fig. 3. This tongue is provided with a cutting edge D, and functions as a chisel or plow in cutting out the desired groove in the mortar between bricks.

One end of the body is kerfed into two portions, one of which remains in the plane of the body and is equipped with a cutting edge E, the other is bent at right angles to the plane of the body and extends in a direction oppositeto that of the tongue, is provided with a cutting edge, and designated as F. These two portions are designed for cutting out mortar in places not easily accessible to said tongue.

claim:

1921. 'Serial No. enema,

, The otaer end of the body is provided with an offset linger (1, having. a smooth upper periphery, which, for, the greater portion of its length, is of a width approximately the same as the tongue, and as indicated at Eh it terminates in a cutting edge, denoted by I. "This finger is, utilized as a handle and also as an'instruniientfor smoothing out a groove while the mortar is in a plastic condition. J is used to designate brickwork, K, the face of a rough mortar joint while in a soft state, and L the face of a smooth mortar joint.

In using the device it is placed as, illus trated in Fig. l; the body flush with the brickwork and the tongue extending into said. rough mortar joint. As is obvious, the manual operation of the tool along the course of the joint, and the proper application of force, will cause the tongue C,

with its cutting edge D, to cutout the;

rough joint, permit the surplus mortar to escape through the front of the body by the opening between the tongue and the body, and leave a groove of a uniform width and depth throughout the course of the .joint. When the groove is thus made, the tool can be reversed and the narrow upper portion H of-the offset finger placed in the groove and run along the mortar, thereby imparting a smooth finishto the groove.

The cutting edges E, F and I, add to the effectiveness of the device, inth at with them,

any corners or points not reached conveniently by the cutting tongue, can be readily smoothed. and finished up.

The tool, constructed as it is of a single strip of sheet metal, is inexpensive to produce. It is of light weight and a simple implen'ient of the masons trade; easy to use,

and having no parts which can work loose or give trouble in adjustment. As is evident, the cutting tongue can be offset by bonding to give any required depthto a groove, and all the cutting edges are so located as to render them easily sharpened, when desired. Z

Having thus described my invention, I

1. A device of the class described, comprising a flat body member, having at one end a curved handle provided with a smooth upper surface andav cutting end, the other, end of the body having a section separated intwo portions by a kerf, one portion decutting edge,

fining a cutter extending in a plane approximate y parallel \'ith the base of the handle the other portion extending in the plane or: the body and terminating in a t an integral scraping and ganging member, of a width less tnan the body and not exceeding the Width of the upper surface of the handle, offset from the body in n direction oppositely to said first pen tion, and terminatin in at cutting edge.

2. i jointing tool made of at single piece of sheet metal, having a flat body, conn cted thereivith, an offset cutting tongue of it Width less than the body, an offset ii. having it smooth upoer surface of at Width no greater than the tongue, adapted to serve as a handle and a surfacer for plastic meterial, end an angulzirly disposed cr er extending from "the bed) in a direct ion oppositely to that of the tongue.

3. A device of the class described of in tegral construction having a body provided 1,etd5,021

in its medial portion with an offset tongue terminating in e cutting edge, adapted to cut out and gauge a groove in plastic material, a at one end of the body and terminating in a cutting edge, for surfacing said groove and a right angular portion at the terminating in e cutting edge, to engage corners.
